Migrating to higher stable versions should be one of the applications priorities, as switching from 5.6 to PHP 7 will be much easier than switching from PHP 4.0 to PHP 8 (the version to be released). The period of accommodation of regular programmers with PHP 5.6 should be relatively short depending on their level of training because the syntax and the way the language works remain the same. This argument is a very wrong one, because programming is constantly changing, and the stable higher versions of programming languages will always add to the applications and reduce the actual development time. Features like new operators, anonymous classes etc.). Most PHP 5.6 users fear that migrating to PHP 7 will make the development process more difficult in the first months due to the introduction of new features that are not known to programmers. This analysis is very important to be able to replace the functions that are removed in the new version of PHP, a lack of this analysis can lead to the collapse of the application with its migration to the new version of PHP (risk of filling log files with warnings / errors / notices, blocking execution flows due to calling a non-existent function and other issues).
